Anemia is a condition of insufficient oxygen carrying capacity of blood or red blood cells



Quick Facts


Red blood cells or RBCs are formed inside bone marrow, the central part of the bones

A single RBC has a lifespan of about 100 days.

The bone marrow starts producing RBCs when it receives the signal from kidneys which release a protein directing bone marrow to do so In addition to the signal from kidneys, the bone marrow needs adequate supply of certain vitamins, minerals, and nutrients to produce RBCs. The three most important such elements are iron, vitamin B 12, and folic acid.

The commonest causes of anemia are iron deficiency, rapid destruction of RBCs, chronic diseases of internal organs like kidneys, cancer, defective RBCs, and bone marrow disease.


When to suspect anemia?


Anemia may not have any symptoms when mild. The first symptoms that might appear include:


  • Weakness and irritation
  • Headaches
  • Easy fatigability
  • Brittle nails
  • Perverted taste
  • Dizziness
  • Pale skin color
  • Shortness of breath
  • Heart conditions


Confirmation of Anemia

  • Low blood pressure, especially related to change in posture
  • Pale skin
  • increased heart rate
  • Blood test confirmation
  • Bone marrow studies

Other tests may be done to find medical problems that can cause anemia.




Treatment should be directed at the cause of the anemia, and may include:

  • Erythropoietin
  • Iron, vitamin B12, folic acid, or other supplements
  • Blood transfusions


When to Contact a Medical Professional


Anemia should be considered as a process that may develop either slowly or suddenly and the symptoms and signs vary accordingly. Blood tests generally give a clue as to the type and extent of defect leading to anemia.

 One should get in touch with a healthcare under following situations:

  1. Detection of any of the symptoms of anemia or any unusual bleeding from any site in the body.
  2. Kidney disease or heart disease
  3. Medication known to damage RBCs.
  4. Digestive disorders especially in which food components are not properly absorbed from the gut.
